Foldable Canvas Blank With Hinged Locking Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional canvases are heavy, expensive, and difficult to store without causing damage to the canvas and the painted image due to the repeated mounting and unmounting process from wooden stretcher frames.
Innovation Solution
A foldable canvas blank with a working panel and flexible hinged panels that can be easily folded into a compact form, using hinges and locking slots to secure the panels in place, allowing for easy storage and use without the need for a stretcher frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional canvases are made with wooden stretcher frames, then the canvas maintains rigidity for painting, but the canvas becomes heavy and difficult to store
Solution Approach 1:
The canvas is divided into modular components: a working panel and detachable frame elements. The frame is segmented into side panels and end panels that can be separately attached and detached, allowing the canvas to be disassembled for storage while maintaining rigidity when assembled for painting.
Solution Approach 2:
The canvas frame transitions from a static traditional wooden stretcher to a dynamic, reconfigurable structure. The frame panels can be flexibly attached and detached through hinges and locking slots, enabling the canvas to adapt between a rigid painting state and a compact storage state.
2Ease of operation
If traditional canvases are repeatedly mounted and unmounted from wooden stretcher frames, then storage is possible, but the canvas and painted image deteriorate
Solution Approach 1:
The canvas frame is pre-configured with attachment and detachment mechanisms (hinges and locking slots) that enable easy assembly and disassembly without requiring forceful manipulation. This preliminary design of the connection system prevents damage during storage operations.
Solution Approach 2:
The frame panels are designed with flexible attachment points that allow the canvas to be easily assembled and disassembled without stressing the canvas fabric. The flexible hinges and locking slots enable gentle manipulation that protects the painted surface.
3Stability of the object's composition
If traditional canvases use wooden stretcher frames, then structural stability is achieved, but cost increases
Solution Approach 1:
The frame structure uses composite construction combining rigid panels for structural stability with flexible hinge mechanisms and locking slots for ease of assembly. This composite approach replaces expensive traditional wooden stretchers with a more cost-effective multi-material system that maintains structural integrity.
4Ease of operation
If the canvas is made foldable with hinged panels, then storage convenience is improved, but device complexity increases
Solution Approach 1:
The frame panels are designed to nest together when folded, with side panels and end panels fitting into compact configurations. The locking slots and insertion tabs enable the panels to interlock in a nested arrangement, achieving compact storage without excessive complexity.

AI summary
A foldable canvas blank includes a working panel, the working panel comprising a top end, a bottom end, a right side, and a left side; a top end panel flexibly attached to the top end by a first top end hinge, the top end panel defining a top end locking slot extending through the top end panel; and a right side panel flexibly attached to the right side by a first right side hinge, the right side panel defining a right side edge surface distal from the working panel, the right side panel defining a right side locking slot, the right side locking slot intersecting the right side edge surface and extending inwards towards the working panel, the right side locking slot configured to engage the top end locking slot to secure the top end panel to the right side panel.
